The length of life of a person depends to a certain extent on the strength of the heart function and the level of lung capacity (the degree of expansion and contraction of the chest cavity). People who love exercise will have strong heart function and high lung capacity, which can reduce the aging of the body to a minimum. Conversely, people with fast heartbeats have a weaker heart function and their blood output is relatively reduced, leading to faster aging.
If a person sits for a long time without paying attention to activities, it may cause many diseases, such as:
As the body's demand for the workload of the heart decreases, it may lead to myocardial weakness, hypofunction of the heart, and slower blood circulation, leading to hypertension and laying the root of coronary artery embolism.
Due to the obstruction of the venous return of the rectum and anal canal, it is easy to cause blood stasis, vein dilation, and hemorrhoids.
The muscle function is affected, causing the muscle to relax and weaken. Due to the reduced blood flow and insufficient oxygen supply to the muscles, muscle stiffness, soreness, and even atrophy can also be caused.
Due to poor blood circulation in the buttocks, coupled with unclean skin, buttocks boils are prone to occur.
Sitting for a long time causes the weight of the whole body to be pressed on the bottom of the spine, and the pressure bearing surface is unevenly distributed, which can cause the sagging of the back and abdominal muscles, resulting in lower back muscle pain and indigestion.
Sitting for a long time weakens the peristalsis of the colon, prolongs the residence time of stool in the colon, and prolongs the contact time of carcinogens and colon mucosa, which makes colon cancer prone to. In addition, the number of human immune cells that prevent diseases and cancers also increases with the increase in activity. Sitting for a long time will hinder the production of immune cells.
